"You are obviously passionate about animals. Is there one that you're like, 'I'm a little less keen?' Tim asked Rob.
"It's funny," Rob replied with a smile on his face.
"I will say I love all animals, and I absolutely love them to death, there's not an animal that I don't just love. But there are some animals that don't love me particularly well."
Rob went on to add that he had "a thing with wombats," much to the disbelief of viewers tuning in from home.
"Wombats try to kill me. They're not just aggressive, no, they try to kill me," the teenager admitted before adding that crocodiles were much easier to "deal with" because "wombats are crazy."
"They're insane, they can run 40km an hour," he added.
"Don't trust a wombat."
But despite his apparent reservations about the native Australian animal, Rob proved that he was his father's son through and through as he shared some words of wisdom from the heart.
"Something that my dad always said and something that will stick with me forever was, 'Treat every living being the way you wish to be treated."'
"Except wombats, because they have a thirst for blood," he joked.
